[0022] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0023] like Figures 1 to 4As shown, the present invention provides a built-in slip ring rotating motor with integrated water and gas cooling functions, which includes a motor housing 1, a gas delivery assembly 2, a stator assembly 3 arranged in the motor housing 1 and connected to the inner side wall of the motor housing 1, an end cover 4 covering the top opening of the motor housing 1, a rotor assembly 5 arranged in the hollow middle of the stator assembly 3, and a power supply device 6 for transmitting electrical signals and / or power to the rotor assembly 5 and / or the stator assembly 3; the rotor assembly 5 is connected to the inner side wall of the end cover 4; The gas delivery assembly 2 includes an inner shell 7 arranged in the motor housing 1 and connected to the inner side wall of the motor housing 1, a first air channel 8 arranged in the inner shell 7 and a third air channel 10 arranged in the end cover 4. The end cover 4 protrudes into the inner shell 7 and is rotatably connected to the inner shell 7. The inner side wall of the end cover 4 and the inner side wall of the inner shell 7 form a ring-shaped second air channel 9. When the rotor assembly 5 drives the end cover 4 to rotate relative to the inner shell 7, the second air channel 9 can always remain connected with the first air channel 8 and the third air channel 10.

[0024] Specifically, the internal slip-ring rotary motor further includes a gas drive device for supplying or drawing gas into the first air passage 8. The end cap 4 includes a cap body 11 connected to the rotor assembly 5 and a rotating shaft 12 disposed on the cap body 11. The rotating shaft 12 is inserted into the inner shell 7 and rotatably connected to the inner shell 7. The second air passage 9 is an annular air passage formed by the circumferential sidewalls of the rotating shaft 12 and the inner sidewall of the inner shell 7. The third air passage 10 includes a fifth air passage 14 disposed within the cap body 11 and a fourth air passage 13 disposed within the rotating shaft 12. The fifth air passage 14 communicates with the second air passage 9 via the fourth air passage 13. The inner sidewalls of the motor housing 1 and the outer sidewalls of the inner shell 7 enclose an installation space, and the stator assembly 3 and rotor assembly 5 are located within the installation space. A pneumatic device is a device that uses compressed air as a power source to drive a mechanical structure to perform telescopic or rotational movements, such as a cylinder or pneumatic gripper. The adsorption device is a device that relies on air pressure difference to allow mechanical components to adsorb the workpiece to be processed, such as a vacuum adsorption platform or suction cup.

[0025] During actual use, the workpiece to be processed is stably mounted on the cover body 11 through a pneumatic device or an adsorption device, and the rotor assembly 5 and / or the stator assembly 3 are powered by the power supply device 6, so that the rotor assembly 5 rotates relative to the stator assembly 3, and the rotor assembly 5 drives the cover body 11, the rotating shaft 12, the workpiece to be processed and the pneumatic device or the adsorption device to rotate relative to the motor housing 1 and the inner housing 7, thereby realizing the free rotation of the product to be processed and facilitating the processing of the product to be processed. In addition, when the gas drive device adopts an air supply device such as an air pump, an air pump, or an air compressor, the output end of the gas drive device is inserted into the motor housing 1 and air is supplied to the air inlet of the first air duct 8, and then the air outlet of the fifth air duct 14 is connected to the pneumatic device. The pneumatic device is a device such as a cylinder and a pneumatic clamp. The gas output by the gas drive device flows in the first air duct 8 to the second air duct 9, the fourth air duct 13 and the fifth air duct 14 in sequence, and flows out from the air outlet of the fifth air duct 14 to the pneumatic device. The gas drive device provides pneumatic force to the pneumatic device through the fifth air duct 14, thereby providing power for the operation of the pneumatic device. Conversely, when the gas-driven device utilizes a suction device such as a vacuum pump or a negative pressure machine, the outlet of fifth air channel 14 is connected to a suction device such as a suction cup. The gas-driven device draws gas from first air channel 8, and the gas from fifth air channel 14, fourth air channel 13, and second air channel 9 flows into first air channel 8. The gas-driven device draws gas from the suction cup or other suction device through fifth air channel 14, providing negative pressure or suction force for the suction device. The gas flowing through first air channel 8, second air channel 9, fourth air channel 13, and fifth air channel 14 continuously removes heat from motor housing 1, improving the heat dissipation efficiency of the rotating motor and reducing deformation caused by thermal expansion and contraction of components within motor housing 1. The present invention is highly practical, highly efficient, and easy to manufacture and process. The first air duct 8, the second air duct 9, the fourth air duct 13 and the fifth air duct 14 are opened on the motor housing 1, the inner housing 7, the rotating shaft 12 and the cover body 11. When the rotating shaft 12 rotates, the fourth air duct 13 can always keep in communication with the annular second air duct 9. The rotating cover body 11 and the rotating shaft 12 will not interfere with or affect the air supply or air intake of the first air duct 8, the second air duct 9, the fourth air duct 13 and the fifth air duct 14. The gas transportation of the first air duct 8, the second air duct 9, the fourth air duct 13 and the fifth air duct 14 is stable, and there is no need to reserve space and position for installing the air pipe in the motor housing 1, which reduces the volume of the motor housing 1 and makes the structure of the rotating motor more compact.

[0026] like Figure 1 As shown, further, the built-in slip ring rotating motor also includes an air duct interface 15 set through the motor housing 1, and the air duct interface 15 is connected to the first air duct 8.

[0027] Specifically, the cover body 11 is provided with an airway interface 2 16, and the fifth airway 14 is connected to the pneumatic device or the adsorption device via the airway interface 2 16. In actual use, when the airway interface 2 16 is connected to the pneumatic device, the output end of the gas drive device is connected to the airway interface 1 15, and the gas output by the gas drive device flows into the first airway 8 through the airway interface 1 15. The gas flows through the second airway 9, the fourth airway 13, the fifth airway 14 and the airway interface 2 16 in sequence, and flows into the pneumatic device through the airway interface 2 16. The addition of the airway interface 15 and the airway interface 2 16 facilitates the connection between the gas drive device and the first airway 8, and facilitates the connection between the pneumatic device or the adsorption device and the fifth airway 14, saving the time of connecting and debugging the gas drive device, the pneumatic device or the adsorption device and the rotating motor.

[0028] like Figure 3 As shown, further, the gas delivery component 2 also includes a circumferential sealing structure 17 sleeved on the rotating shaft 12, and the sealing structure 17 is embedded in the inner wall of the inner shell 7. The sealing structure 17 includes two seals arranged on both sides of the second air duct 9 in an upper and lower manner. The two seals cooperate to seal the gap on both sides of the second air duct 9.

[0029] Specifically, there are two sets of gas delivery assemblies 2; the gas drive devices connected to the two sets of gas delivery assemblies 2 can respectively adopt a gas supply device and / or a gas suction device. In actual use, the sealing member can adopt a sealing ring. The sealing structure 17 seals the second air channel 9 to prevent gas in the second air channel 9 from leaking out of the second air channel 9, thereby improving the airtightness of the second air channel 9 and reducing gas loss or waste in the second air channel 9.

[0030] like Figure 4 As shown, further, a spiral channel 18 is provided in the motor housing 1 .

[0031] Specifically, the motor housing 1 is provided with a water inlet and a water outlet. Coolant is continuously introduced into the spiral channel 18 through the water inlet, and the coolant in the spiral channel 18 then flows out of the motor housing 1 through the water outlet. The coolant continuously removes heat from the motor housing 1 to continuously cool the motor housing 1, further avoiding the problem of excessive heating of the rotating motor and extending the service life of the rotating motor.

[0032] Furthermore, the power supply device 6 includes a slip ring rotor 19 connected to the rotating shaft 12 and a slip ring stator 20 provided on the inner shell 7 , and the slip ring rotor 19 is inserted into the slip ring stator 20 and is rotationally connected to the slip ring stator 20 .

[0033] Specifically, the slip ring rotor 19 always remains electrically connected to the slip ring stator 20 when rotating relative to the slip ring stator 20 . During actual use, the signal line or / and electric wire passes through the motor housing 1 and the inner housing 7 in sequence and then is connected to the slip ring stator 20. The signal line or / and electric wire is used to supply power or / and transmit electric signals to the slip ring stator 20. The slip ring stator 20 supplies power or / and transmits electric signals to the rotor assembly 5 through the slip ring rotor 19, so that the rotor assembly 5, the cover body 11, the rotating shaft 12 and the slip ring rotor 19 rotate relative to the motor housing 1 and the inner housing 7. The slip ring rotor 19 always maintains an electrical connection with the slip ring electronics during the rotation process. While the slip ring stator 20 and the slip ring rotor 19 supply power or / and transmit electric signals, the signal line or / and electric wire will not rotate with the rotation of the slip ring rotor 19 in the motor housing 1, thereby preventing the signal line or / and electric wire from being entangled, knotted, pulled or broken in the motor housing 1 or the inner housing 7, thereby reducing the risk of wear of the signal line or / and electric wire, reducing the risk of short circuit of the signal line or / and electric wire, reducing the number of repairs and maintenance of the rotating motor and reducing costs.

[0034] like Figure 4 As shown, further, the power supply device 6 includes a weak-current conductive part 21 and a strong-current conductive part 22 arranged at intervals in the upper and lower parts, the strong-current conductive part 22 includes a plurality of strong-current conductive rings arranged at intervals on the slip ring rotor 19 and a plurality of strong-current brushes electrically connected to the strong-current conductive rings in a one-to-one correspondence, and the strong-current brushes are arranged on the slip ring stator 20; the weak-current conductive part 21 includes a plurality of weak-current conductive rings arranged at intervals on the slip ring rotor 19 and a plurality of weak-current brushes electrically connected to the weak-current conductive rings in a one-to-one correspondence, and the weak-current brushes are arranged on the slip ring stator 20.

[0035] In actual use, a plurality of signal input lines or wires for transmitting strong electric signals or / and delivering high voltage electricity are sequentially passed through the motor housing 1 and the inner housing 7 and then electrically connected to the strong electric brushes, and a strong electric signal or / and a strong current is delivered to the slip ring stator 20 and the slip ring rotor 19 by the signal input lines or / and wires for transmitting strong electric signals or delivering high voltage electricity; a plurality of signal input lines or / and wires for transmitting weak electric signals or / and delivering low voltage electricity are sequentially passed through the motor housing 1 and the inner housing 7 and then electrically connected to the weak electric brushes, and a weak electric signal or / and a weak current is delivered to the slip ring stator 20 and the slip ring rotor 19 by the signal input lines or / and wires for transmitting weak electric signals or / and delivering low voltage electricity. The strong electric conductive portion 22 and the weak electric conductive portion 21 are spaced apart up and down, which can effectively reduce the interference of the strong electric signal or / and the strong current in the transmission process of the weak electric signal or / and the weak current, and improve the stability of the power supply device 6 when transmitting strong electric signals and weak electric signals simultaneously.

[0036] Furthermore, the built-in slip ring rotating motor further includes a wire passing channel 1 24 provided in the cover body 11 and a wire passing channel 23 provided in the rotating shaft 12 , and the wire passing channel 1 24 and the wire passing channel 2 23 are communicated with each other.

[0037] During actual use, the slip ring rotor 19 is connected to a wire for outputting an electrical signal. The wire can extend from the wire passing channel 2 23 into the wire passing channel 1 24, and extend from the wire outlet of the wire passing channel 1 24 to the outside of the cover body 11. The wire on the slip ring rotor 19 is led out of the cover body 11 through the wire passing channel 1 24 and the wire passing channel 2 23, which facilitates the routing and wiring of the wire, reduces the number of devices such as wire harnesses required for wire collection, and saves production costs.

[0038] Furthermore, the built-in slip ring rotating motor also includes an encoder 25 mounted on the inner shell 7, and the end cover 1 4 also includes a second rotating shaft 26 connected to the end of the rotating shaft 12 away from the cover body 11, and the second rotating shaft 26 protrudes into the input end of the encoder 25.

[0039] Specifically, the cover body 11, rotating shaft 12, and rotating shaft 26 are sequentially rotated from top to bottom within the inner housing 7. Rotating shaft 26 penetrates the hollow space of the slip-ring rotor 19 and protrudes into the input end of the encoder 25. The internal slip-ring rotary motor also includes an end cap 27 covering the bottom opening of the motor housing 1. The encoder 25 penetrates end cap 27 and protrudes out of the motor housing 1. The encoder 25 can be a Tamagawa encoder 25. In actual use, the cover body 11, rotating shaft 12, and rotating shaft 26 are driven to rotate by the rotor assembly 5. The encoder 25 detects the angle and speed of rotation of rotating shaft 26. The encoder 25 is easy to install and connect to the inner housing 7, and rotation detection of rotating shaft 26, rotating shaft 12, and the cover body 11 is convenient and quick. The encoder 25's placement through end cap 27 conserves internal space within the motor housing 1, making the internal structure of the motor housing 1 more compact.

[0040] All technical features in this embodiment can be freely combined according to actual needs.

[0041] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
